Hello Victor,
that plan won't work. These devices have protection diodes at the input. As soon as the input voltage is exceeding the supply range, these diodes start to conduct. An input higher than Vdd will lead to a current into the Vdd-net, an input lower than Vss will lead to a current to Vss.
As long as you limit the current with a series resistor to an allowed value (e.g. 30mA for the ADG714) the device will not get defect. But nevertheless you will load your input with this current.
best regards
